To all 'whom it 'may concern! Be it known that LIBERNARD LIBERMAN, a citizen of the United States, residing `at Philadelphia, in the county of Philadelphia, State of Pennsylvania, have invented a new and useful methodA and means for Cigar- Buncliing, of which the'following is a speci- Y fication;

-.My invention relates-to cigar bunching; The object isto provide improved method and means whereby a measured charge of tobacco is received from the ,supply,*sepa-, rated from said supply and delivered to the bunching table in such a way that the charge shall have an approximately even density throughout. To this endt'he invention comprises method and means for pushing the charge evenly into the measuring pocket and preventing a portion of the charge from being packed or unduly compressed at one side of the pocket.

- The invention is an improvement on the y method and means described and claimed in the pending` application filed by Bernard a bunchng machine showing my "inventioii;lv

Liberman on Nov. 24:, 1920, having Serial No. 426,184. In that device the measuring pocket was provided, along one longitudinal margin thereof,with a severing knife, which was adapted to cooperate with means forming a cutting edge arranged ladjacent to one margin of the hopper opening which discharged to said measuring device. In

the operation of such a .device it was found that, as the measuring device rotated relatively as to the hopperpopening, the tobacco lying inv the' top of the measuring pockety was pushed or scraped toward the side of the pocket containingv thek knife. This resulted in carrying away solne of the tobacco that should normally lie in the pocket near the opposite margin, vandin unduly coinpressing and packingrthe tobacco toward the side of the pocket having said knife. The result was an uneven distribution 'of the tobacco in the pocket and consequently an irregular and uneven ,charge "for lthe bunch.Y I have overcome this objectionxby the following method, and the means for effecting the same, herein described.'

Referring to the drawings, which illustrate 'merely by way ofe'Xample, suitable means for effecting my invention Fig. 1 is a vertical section ofthepartof Fig. 211s a.fragmentaryr section showing f parts in different position.`

VFigo is an elevation of same after the measuring device has made a little more than a'quarter turnfrom the position shown in Fig. 1.

Fig; 4 is a vsectionv on line Ll-Ll of Fig. 3.r

Fig.A 5 'is a perspective view, on an enlarged scale, ofthe improvement.

*Similar numerals refer to similar parts throughout the vseveral views. i'

The lower vportion Aof'the hopper, lindicated at, is adapted to discharge to the measuring device whichV comprises the rotating element? seated in thefarc-shaped flanges 8 of the hopper 6 and provided withv the pocket 9.` Thedepth of the pocket ris adjusted by the member 10, operated by the screw 11, having the knurled head 12. One

margin of this pocket `r9.is provided with.

thel 'plate -15 lis vclamped the recessed ele-` ment 17 having ra curved and inclined formationl or wall, as at'18, extending to the periphery Ofelement 7,:as at 19, and provided at thisfpointwith the knife 20 having its edge adapted tofcooperate withthe edge" of knife as 2l y The curved wall 18,'is ,proyided'with thewflankiug walls 21 element comprising my which'engagedthe* rotating' element 7 approximatelyfat.leachfend ofv the pocket 9. Asshown inI ,Figs-1l and`2 the rotating ele ment 7 is adapted ltorotate inthe counterclockwise.direction lfrom .the position, as in lFigl1,i`n which itreceives the charge from the hopper 6, to the position as in Fig. Ll-,to discharge to the trough 22, whichin turn delivers to .thef'funnel or other means for carrying the. charge to' the bunching apron,

In operation 7h63 throtating element 74 sin the por Y sition shown in Fig. 1, its pocket 9 is lilled with scrap tobacco from the supply contained in the hopper 6. As the element 7 then rotates in the direction of the arrow shown in Fig. 1, the tobacco which is stationary inthe hopper tends to separate from the tobacco which is contained' in the pocket S), and, as the hopper approaches the position shown in Fig. 2,v whatever tobacco -is carried by the pocket away from the main supply contained in the hopper, is brought into the recess formed between the rotating element 7 and the inclined wall 18. As the element 7 continues to rotate, the knife edge 13 approaches, and finally reaches the knife edge 20, so that the major portion of the tobacco that lies between the top margin of the pocket and. the inclined wall 18 is pressed into a no rmal plane corresponding with the top of the pocket before the knives 13 and 2O cooperate to completely sever the ycontents of the pocket trom the supply. 1n other words nearly all of the tobacco which is carried trom the main body contained in the hopper, and which would tend to. be scraped fromthe, top ot the pocket, or project above the plane oi its. top margin will be gently and evenly pressed bythe inclined and nearly tangential wall, before the edges 13 and 2O come together with a shearing` action.Y

Vhat l; claim is 1f. In the art of bunching, the method of separating measured charges ot scrap tobacco. trom a supply7 which consists in pressing evenly in-to a normal plane, the exposed surface ot' the measured charge which projects above said normal plane, and; then severing the body ot" the charge 'from the supply.

2. in a scrap bunching machine, the coinbination of an element provided with a measuring pocket, movable to and from the receiving positionyand the discharge position, means tor delivering scrap. to said pocket, means connected therewith -torn'iing aninclined wall extending toward the margin ot the pocket as it approaches the discharge position for gradually and progressively pressing evenly into a normal plane a projecting portion of the charge, and cooperating lnives associated with the margin of the pocketvand the margin of said inclined wall respectively for severing portions of scrap projecting above said normal plane.

Means: 'for delivering measured` charges ot scrap tobacco for cigar bunching, comprising a rotating element having a measuring pOCket, a hopper delivering thereto, means associated with said .hopper forming a curved surface adjacent the delivery opening of the hopper and in the line ,of travel' of the pocket and approximately tangential to the -peripliergcf the rotatingelement,

means for evenly pressing the filler into the pocket as the same moves away from the body ot' filler in the hopper, and means forming cooperating knives tor severing the measured charge from the supply.

'-1. Means for delivering measured charges of scrap tobacco for cigar bunching, comprising a rotating element having a measuring pocket provided with a cutting edge at its rear margin, a hopper delivering thereto, means associated with said hopper torming `a recess with a. curved surface, adjacent the delivery mouth of the hopper approximately tangential tothe peripheryof the rotating element, and provided with means forming a cooperating cutting edge adjacent the periphery oit rotating element.

5. Means 'for delivering measured charges ot' scrap tobacco for cigar bunching7 comprising a rotating element having a measuring pocket provided with a cutting edge at itsY rear margin, a hopperdel-ivering thereto, means associated with said hopper torming a recess with a curved surface, adjacent the delivery mouth of the hopper appro-Ximately tangential to the periphery of the rotating element, and provided with means forming a cooperating cutting edge adjacent the periphery of rotating element, said cooperating cutting elements inclined to each other to give a shearing' action.

6. Means for delivering measured charges oi scrap tobacco` for cigar bunching, comprising a rotating element having a measuring pocket provided with a cutting edge at its rca-r margin, a hopper delivering thereto, means associated with said hopper `ii'orming a recess with a curved surface, adjacent the delivery mouth of; the hopper approximately tangential tol the periphery of the rotating element, and provided with means forming a cooperating cutting edge adjacent the periphery oft" rotating element, said cutting elements cooperating to sever portions ot scrap projecting from the pocket.

7. In a scrap bunching machine, the conibination of means forming a measuring pocket, movable to and from receiving and discharging positions a hopper for delivering scrap thereto, means `forming an oiiset recess at the hopper base hav-ing a wall converging toward the pocket providing means whereby the scrap in the offset recess is pressed into the pocket as the pocket moves toward the discharging position., and cooperating lniives arranged and operated-to shear oit all tobacco projecting from the pocket as the pocket passesbeyond the oit"- set recess. j.
